' MECHANISM FOR APPLYING BOTTLE-CAPS. I

lballivhom'itmayfconccm: l Be it known that I, J oi-IN D. Lonn, a c1t1- zen oflthe United States, andfresident of Qthe. borough of Brooklyn, county ofKings, g'city and State .of New York, have invented certain new and useful, Improvements in Mechanism for Applying Bottle-Caps, of which the following is aspecification.

My invention relates toa crimping device or check for applying-caps to bottles and has for its object to provide a very simple and eliicient device of this character.

' Reference is to be had to the accompanyingdrawlngs in which- Figures 1 and 2 are longitudinal sections showingone form of my invention in two different operative positions; Fig. 3 1s asimilar view with only the casing and guide inscction and with the parts in the position of'ltesttl iig. 4 is albottom view with the I parts in the position shown in Fig. 2, the

bottle beiiw omitted Fi at is a similar.

bottom view with the' parts in 'the position shown in, Fig. 1, and Figs. 5 and (i are bot- -tom"v1cws of two other forms of my invention.

' indicates a bottle which at its mouth is 4' provided with the well-known bead to produi-e an outwardly Haring-surface adapted to hold the lower edgefol the cap \\'l1l( 'll is crnnped under it. The cap 13 may be Sllll' ply in the shape of a disk with a cylindri- -cal fla nge dcpendlng from its outer. edge,

sa-i cap containing a washer or packing if esired. ='lhc chuek employed by me comprises a plunger head 0 adapted to engage the cap as shown in Figs. 1 and 2. This head is connected as by means of a screw D with .a d sk: E projecting slightly beyond the ad- 'jacent{faceof-the head. and adapted to rest against an annular lip'or shoulder l on the 7 .guide F. The said guide is providedwith a flaring inner surface F which is adapted to engage a corresponding outer surface G'- upon a series of crimpiiw jaws G. Each of these ja'ivsisprovided atits upper end with a finger G? seated in an annular recess C of thehcad C in "such a manner that the connection of the jaws with the head is -pract1cally a pivotal one, that is, each jaiv may rock about its-upper end. -The guide F j hasan' outward pro ection Ffleugaging a corresponding interior shoulder in the annular-casing wlnch 18 provided at its lower endwith an opening 11 through which the bottle mouth with the cap may be inserted. The guide Fis forced against the shoulder of the casing II by means of a cap J screwing into the upper end of the casing H.

With this cap is rigidly connected a stem 'K and a coiled spring L is interposed betweenthis stem and the disk E which spring'therefore has a tendency to move the said disk against the lip F. .the lower ends of the jaws, each of which is provided with a small groove toreceive said spring which tends to bring the jaws together attheir lower ends asshown in A spring M surrounds Fig. It will therefore be understood that I the parts 1, II, J and K are rigidly c01mect-' ed in the normal operation of the machine, while the parts C, l), E are movable verti cally in relation to those-first mentioned and the jaws .G are capable of a slight vertical movement and furthermore of a rocking movement as hereipbefore' referred to. The stem or rod K is connected with a mechanism suitable for imparting a vertical motion to it; a hydraulic press, orany other-3b press is available for this pin nose.

. It will be noticed that eac i of thejaws G is provided at its lower end upon-its lll ner surface with a crimping portion G ()ne. of the jaws, however, instead of l1.-ivi||g 35'- such a projection, is cut out or recessed as shown at- G in Figs. 2, 4 and at.

The action of the apparatus is'as follows: The parts at first occupy the position shown in Fig. 3 with the jaws G held closely .against each other by the spring M and the head 0 in its lower position under theinflu-z. ence of the spring L As the chuck" descends the cap B will fit between the crimping pro- 'ections G of.,.the 'aws-G-andsince the- .l 1

spring M is q ti-te-weak, the jaws will sprin outward as illustrated in Figs. 1 and 4. If then the chuck descends farther, the motion of the head Cjb mg stopped by'the cap end of the chuck-and "the parts connected therewith rigidly will "continue 'to-in'ove downward, compressing the spring L and causing" to swing inward at their lower ends so that 1.05 the flange of the cap-B is bent or-crimped under the head of the bottle neck as shown in Figs. 2 and 4 at all points except where the recess G occurs. At this point thefian e of the cap will 'retain approximately ,as

'of thebottle, it' follows thatpnlythe casing v original diameter and will. thus form on the finished cap, a projection or lip standing away from the lower edge of the cap and from the bottle (seeiFig. 2) andthus afford a convenient means for engagement by a-g-tool used in removing the cap.- In the final position illustrated by Fig. 2 the-outer surface of the head and the inner surfaces ofthe jaws G are preferably in close engagement with each other as. shown. It will be understood that-the movement of the jaws G from the'position as shown in Fig. 1 to that shown in Fig.2 is due to the action of the inclined In Fig. 5 I have shown a construction .in

which three aws instead of one are provided with cut-outs. G, the cap crimped with this chuck would therefore have three1lips in stead of one,

' In Fig. 6 I have illustrated another construction in which adjacent corners G of two adjoining jaws G are cut out or recessed to form together pointed recesses "which will result in the formation of'corre- I sponding lips on the cap. F ig. 6 shows four such recesses, but it will be understood that a greater or smaller number of them may be provided and-even one such recess will be suflicient. 7

It will be seen that the device is very simple and affords great advantages as to the application and crimping of the bottlev capand moreover the chuck is readily separable.

For thispm'pose the cap J can he unscrewed which will leave the guideI free to be removed with the -jaws and the head C fiIfid by removing the screw-D the jaws G, the

other and from the guide F so that either part will be individually accessible. The jaws G are not connected with each other-in any manner except by the spring M- and even this spring fits them looselyl I claim: 1. In a device for applying caps to receptacles a non-rotatable head, members carried thereby loosely and movable relatively thereto toward the cap, said members being arranged with their-side surfaces substantially in engagement with each other, the inner surfaces ofsaid membersabeing constructed differently, so that some will affect the cap, I

2. The combination ofa'non-rotatable head, members mounted to swing relatively thereto and arranged with-their side 'faces substantiallyin engagement with each other, sundry of said members having crimping projections at theirinner surfaces, whileone or more of said members are devoid of such projections and meansf'or simultaneously swlnging'allof said members inward.
